Hi,
I can successfully install one wildcard. But when I want to install two
wildcards, the latter one will replace the first one. For example:
match=parser.OFPMatch(ipv4_dst=('10.0.*2*
.0','255.255.255.0'),eth_type=0x800)
actions=[parser.OFPActionOutput(5)]
inst=[parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,actions)]
mod=parser.OFPFlowMod(datapath=datapath,table_id=1,priority=1,match=match,instructions=inst)
datapath.send_msg(mod)
match=parser.OFPMatch(ipv4_dst=('10.0.*3*
.0','255.255.255.0'),eth_type=0x800)
actions=[parser.OFPActionOutput(5)]
inst=[parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,actions)]
mod=parser.OFPFlowMod(datapath=datapath,table_id=1,priority=1,match=match,instructions=inst)
datapath.send_msg(mod)
There will be only one wildcard, whose match is (10.0.3.0, 255.255.255.0).
But when I tried different priorities:
match=parser.OFPMatch(ipv4_dst=('10.0.*2*
.0','255.255.255.0'),eth_type=0x800)
actions=[parser.OFPActionOutput(5)]
inst=[parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,actions)]
mod=parser.OFPFlowMod(datapath=datapath,table_id=1,priority=*2*
,match=match,instructions=inst)
datapath.send_msg(mod)
match=parser.OFPMatch(ipv4_dst=('10.0.*3*
.0','255.255.255.0'),eth_type=0x800)
actions=[parser.OFPActionOutput(5)]
inst=[parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,actions)]
mod=parser.OFPFlowMod(datapath=datapath,table_id=1,priority=*1*
,match=match,instructions=inst)
datapath.send_msg(mod)
Both rules are installed successfully.
Could anyone tell me why?
